The “Spiderman” star admitted to Howard Stern that he locked lips with Lindsay Lohan several years ago while shooting a movie in New York.

“It was lame,” he told the shock jock Wednesday, adding that Lohan is “delusional” and would probably remember the encounter differently.

Franco may have kissed the “Canyons” star, but the 36-year-old actor insists they never slept together – despite his appearance on Lohan’s infamous sex list.

“I will swear on my mother’s life that I never had sex with her,” he said.

Franco did provide a few dirty details from “a very dark period of her history,” recalling how she used to follow — or, stalk — him around the Chateau Marmont hotel in Los Angeles.

“I’d come home late to the hotel and she’d come find me. I knew which room she was in and I’d see through the window like, ‘Oh there’s another party at Lindsay’s,’ and she would come out to the pool area and find me,” he said.

Then there was the time Lohan actually broke into his hotel room.

“I was on the couch and I open my eyes and there’s Lindsay in my room at 3 a.m. and it’s like okay what do I do now. It sounds so nerdy but I read her a story,” Franco told Stern.

“Yeah, that’s stalking,” he added.

Nowadays Franco is trying to stay away from the drama-prone star.

“Every time I’ve brought her back in my life it’s turned out to be lame and stupid,” he admitted.
